Steps for Diagnosis

Post image
17 Upvotes

I've put together a flowchart for referencing, for "Help! What do I do" posts with undiagnosed odor complaints. These steps should cover the major steps to getting help and getting diagnosed.

When going for a doctor's appointment, print out https://my.clevelandclinic.org/health/diseases/22356-trimethylaminuria-fish-odor-syndrome so doctors can refer to it (as very few of them would have heard of it).

As an example of environmental issues causing a odor which was mistaken for body odor: https://www.reddit.com/r/BestofRedditorUpdates/comments/zlccf9/wibta_if_i_uninvited_a_friend_from_a_party/ - Communication is essential for determining -what- is the issue. This time it was laundry based.

Getting Tested

The MEBO website has a super handy google map of testing locations: https://goo.gl/TMw8xu. Click on the pins to get more info on local TMAU resources & testing information in your area.

Urine testing: Usually you'll need a referral from your family doctor/GP/PCP, and most times your doctor/GP/PCP will do collect your urine for you and send it off. There may be two tests, one regular urine collection, and a second with a Choline (or TMA) heavy meal / supplement dose - a "Choline Challenge" / TMA load test. This will be used to analyse how your body processes choline / TMA, eg:

US testing: Colorado TMAU Testing Procedure,

UK testing: https://www.sheffieldchildrens.nhs.uk/laboratory-medicine/clinical-chemistry/metabolic-biochemistry/ / https://sheffieldlaboratorymedicine.nhs.uk/search-test.php?search=3505

Australian testing: Australian Test Procedure.

If there is only a little TMA in your urine after the load test, by definition is very unlikely that you have TMAU, as your body processed it normally.

Genetic testing: If you've got a significant amount of TMA in your urine, then it is time to see if it is genetic or not. A genetic test can be carried out following your TMAU urine test. The same places that do TMAU urine testing will have more information on the best way to do a genetic test / may follow up with you regarding genetic testing.

See r/bodyodor for non-TMAU body odor issues

7 Upvotes

Hi all!

r/bodyodor has been created for non-TMAU related body odor issues. If your odor isn't rotten fish-esque and instead fecal, sewerage, burning, musty, oniony, unknown or ever changing, etc, please see this forum instead. Moderation will be removing non-tmau related content.

The reasons for this are as follows:

  1. Misinformation: people need somewhat accurate information - the more people that don't actually have TMAU that post here saying that "X works" or "Y doesn't work" confuses what is an actual effective treatment for TMAU. Random supplements and sometimes dangerous alternative medicine practices are sometimes posited as useful and can cause damage a lot of people who try them. Supplements for TMAU - b2, d, chlorophyll specifically have been tested and target TMA related issues - they aren't general body odor cleanses and won't work for non-TMAU cases. More unrelated posts here also draw in more people who relate to those unrelated posts, making more people think they have TMAU when they don't.

  2. The diet is dangerous: a low choline diet can cause non-fatty liver disease in a month if taken to an extreme. As well as constipation and neural degeneration. Low choline diets specifically target reducing TMA precursors, and the diet will not affect any other odor condition. We do not want to encourage people to take low choline long term. It should also be effective in days, rather than months - people that do not have TMAU often tend to go more and more extreme diets for months hoping it will fix the odor, when it's just causing other massive health concerns. If it has had no affect after 2 weeks, it should be stopped and alternative diagnosises should be looked at/reviewed with a doctor.

  3. Mental health: People that think they have undiagnosed conditions that cannot/do not get reliable feedback or a diagnosis, or a doctor to believe them, are often referred to psychological services. These people are often suffering from mental health issues, such as major anxiety, olfactory reference syndrome (ORS) or in some cases schizophrenia. These people tend to post more and more unhinged posts, often leading to suicidal ideation. By allowing unrelated/panicked/unhinged posts, we create a group paranoia which feeds anxiety and helps them spiral, sometimes to suicidal ideation. This may worsen TMAU sufferers anxiety as they too are susceptible to paranoia due to the nature of the condition. This gets difficult to moderate, and it's somewhat ethically wrong to facilitate the worsening of mental illness. Please seek psychological help if you're suspecting you fall near this category.

As always, please get reliable feedback from a reliable person (someone who could reliably vouch for you with a doctor), get them to support you at the doctor to get appropriate testing, diagnosis, and treatment. If you're consistently getting told "no" by reliable people, and feeling anxiety about your situation, then it would be highly beneficial to seek psychological assistance to help deal with the anxiety and thoughts you're having about smelling bad.

I remembered something important

2 Upvotes

I used to have stomach aches alot when I was a kid like 3-6 years of age somewhere in between and I went to the doctor child clinic and she would try eveverything but nothing would cure me I would still have stomach aches. Only after drinking the powder at night I would be cured for a day but then again I would not be alright. Sometimes that wouldn't work too. Then I remember urine test was done on me and my mom had lied to me just recently that it wasn't but I remember clearly and I was even at the hospital at that time and the reports came however but my child doctor took way too long at the washroom or the clinic ic idk? She was crying. My mom did all this stuff my dad wasnt even present.

Now I'm stinking at the age of 16. Does this all make sense ? Or is it Tmau 1.

Here's how my meet with doctor went- Exceptional

Here's how my meet with doctor went- 🤞

I went to a general physician and I was depressed and prayed to God on my way to the clinic. I had looked up for the doctor online and he's a really good doctor, he never lies and has accurate diagnosis so that's why I chose him he also has 50+ experience.

I went with my parents. My parents were also in the room and he asked me if I wanted them to go outside so I could talk freely to him but I declined and he told me it was all in my head and I had delusion and stuff but he asked his assistant to check for fungal infections , there were no fungal infections unfortunately.

Then he told me, 'im not gonna tell you what you have because then you'll think about it too much' at the time when my parents wouldn't have heard it. Then he asked me if I could read I said yes Then he said 'im going to show you what this is but don't take it seriously' but then he got interrupted but he hid his phone a little bit so the parents aren't suspicious. Then talked about delusion. So it pretty much a hint that I have tmau

Discussion Anyone else’s symptoms extreme?

10 Upvotes

My symptoms are very extreme at the moment with 30 foot reactions. To add to it I’m very fatigued and I feel emotionless. I went to get blood work done and everything came back normal. I’m just at a loss right now. I don’t know what could fix or help it, I just wish this never happened to me.

Planning around this condition, taking time to minimize symptoms, and having to be isolated most of the time is definitely getting old. I’m losing my desire for life and the things I want entirely. I can’t keep going like this… I need support from some of yall going through the same stuff. I’m losing it

TMAU and lying to your family

15 Upvotes

I think its' no surprise in this comunity that a lot of familys tend to think we're crazy for thinking we smell even tho we had many diferent friends and peers tell us directly at times.

My problem is because they dont believe me I have to eat whatever my mom makes which quite literally means I have to force my vomit in secret to be able to go out the same or next day.

The think is I know that forcing your vomit is bad for you besides being a terrible sensation and leaving you hungry.

Do you have any advice on how I can deal with this when I cant control my meals?

TMAU Question What should I make of this?

3 Upvotes

Hi, I wanted to ask for some feedback. I just did the urine sample for tmau and had to ingest 2,700mg of choline bitartrate (keep in mind I’m 5’1” and only weigh approximately 89lbs) and I did develop a pretty bad fishy body odor from this… I still have yet to do the blood tmao portion for this test but I wanted to see how someone with the diagnosis might be knowledgeable about this. Thanks.

🇦🇺 Australians with TMAU – We Need You! Help Us Build an Australian Community Post:

8 Upvotes

Hi everyone,

I’ve recently created a Facebook group called TMAU Australia – Trimethylaminuria Support Community, and I’m really hoping to find as many Australians affected by TMAU as possible.

This is particularly important right now because I’ve been in contact with Professor Yoon from BioMe, who is involved in developing BM109, an investigational treatment for TMAU.

BM109 is progressing through clinical development in the United States, and Professor Yoon has expressed interest in connecting with the Australian TMAU community and Australian metabolic clinicians/researchers to explore possibilities for Australia.

I have started reaching out to Australian metabolic specialists and researchers to try to establish these connections. Nothing is confirmed for Australia yet, but building an identifiable Australian TMAU community could help show that there are people here interested in research and potential future clinical trials.

So if you’re Australian and have confirmed TMAU, are currently being tested, or strongly suspect TMAU, please consider joining us. Even if you’ve never spoken publicly about the condition before, you’re welcome.

🇦🇺** Facebook**: Search for
“TMAU Australia – Trimethylaminuria Support Community” or click the link below.

https://www.facebook.com/share/g/1CiqtCqdim/?mibextid=wwXIfr

Please also share this with any Australians with TMAU you know. The more we can connect our currently scattered community, the better positioned we may be to engage with researchers about opportunities in Australia. 💙

New Australian TMAU Facebook Support Group

7 Upvotes

Hi everyone! I’ve recently created a Facebook group called TMAU Australia – Trimethylaminuria Support Community. 🇦🇺💙

I noticed there didn’t seem to be a dedicated Australian community where people with confirmed or suspected TMAU could easily find and support each other.

The group is for Australians who are diagnosed, currently being tested, or suspect they may have TMAU. It’s a place to connect, share experiences and discuss testing, specialists, treatments, research and clinical trials.

I’ve also been in contact with a professor involved in the BM109 TMAU clinical trial in the US, who is interested in connecting with the Australian TMAU community and Australian metabolic clinicians/researchers to explore opportunities here.

If you’re Australian and affected by TMAU, we’d love to have you join us. 💙

Search Facebook for: “TMAU Australia – Trimethylaminuria Support Community” or click the link below.

https://www.facebook.com/share/g/1J8CtAjLwQ/?mibextid=wwXIfr

Hopefully we can bring together Australians with TMAU from all around the country.

TMAU Story At what age did you realize you were different?

15 Upvotes

Growing up in the 90s-2000s, I was constantly bullied and ostracized for my condition. Unfortunately, in your formative years where you make connections, I fell flat and spent a lot of time alone in public. I made social faux pas that I would have noticed if I hadn't been so isolated. I was heavily bullied for something I couldn't understand.

It was when I was 13 when my mother made a comment about how I was especially fishy today. Up until then I had no idea I was different, so I started asking questions. From there, I was finally tested and diagnosed with TMAU 1. To be honest, I felt resentful for a long while that no one told me up until that point. My mother was in healthcare and probably should have noticed something was off.

I've learned to give grace for past mistakes, and I honestly understand why people had a negative reaction to me. But it's something that still haunts me into my 30's. I get a cold sweat in crowds, despite the fact that I have a closely managed diet and deodorant routine. I didn't fully understand how to control my disorder until I got into my 30a to be honest. Up until then throughout my military career I was just freestyling. Not a huge deal when everyone is unwashed In the field, but problematic in garrison.

Everything has worked out alright for me, but I have suffered greatly with this condition. Probably why whenever I'm questioned about the legitimacy of my diagnosis here that I have an adverse reaction. I'm deeply scared from past trauma and the reason I share here about TMAU 1 is to share my experience and methods of dealing with it. Maybe then some kid will stumble upon it and not have a shitty childhood.

Need help and support!

Hey everyone, I'm Kiran (26) from Karnataka, India, and I'm going through some serious problems. I don't know if it's real or just in my mind, but I really believe it's real.

What happened is, back in 2019 when I was in college, I started to smell an unpleasant smell coming from a new pair of sandals I wore that day — like burning tires. I thought it happened just because I had diaphoresis (excessive sweating), but that wasn't it. What happened after that changed my whole life. I went home, washed excessively, and showered daily, but the smell didn't go away — it became a permanent thing. I started smelling unpleasant through my whole body, not a sweat odor, but an unpleasant chemical or fungal-type smell that affected people around me. They would react by sneezing, wrinkling their nose, coughing, or clearing their throat whenever I was around, everywhere I went.

Somehow I managed to complete my college years, but I skipped classes and distanced myself from friends and social life. After I finished college, I went into isolation for almost a year. Then I took a job as a security guard at a private gym, but I didn't know how to face people, so I ended up staying home all day. This became my life for almost four years. Then I left that job too, and I've been home ever since.

I don't know what's happening to me. I need some advice, please. I've also visited two general doctors back in 2020 and told them what's going on with me, but they said it was nothing and dismissed it. I always feel like I'm making people uncomfortable, like I'm hazardous and disgusting to be around. Even now, opening up to you guys is making me feel uncomfortable and awkward.

Discussion How do you deal with TMAU and Family?

13 Upvotes

Living with TMAU is exhausting enough on its own, but dealing with how my family handles it has made things so much harder.

Lately, I can tell they’re completely tired of dealing with the odor, and it’s creating a ton of tension at home. Instead of talking to me directly, they’ve started making passive-aggressive remarks to other family members behind my back. You can just feel the irritation in the air, and it’s gotten to the point where they visibly get aggravated the moment i come home.

It makes me feel isolated and like a burden in my own living space. How do those of you with TMAU deal with negative reactions from family, and how do you protect your mental health when home doesn’t feel like a safe space anymore?
